Question: A plane wall 15 cm thick has a thermal conductivity given by the relationk = 2.0 + 0.0005 T W/(m K)where T is in degrees

A plane wall 15 cm thick has a thermal conductivity given by the relationk = 2.0 + 0.0005 T W/(m K)where T is in degrees Kelvin. If one surface of this wall is maintained at 150 ?C and the other at 50 ?C, determine the rate of heat transfer per square meter. Sketch the temperature distribution through the wall.GIVENA plane wallThickness (L) = 15 cm = 0.15 mThermal conductivity (k) = 2.0 + 0.0005 T W/(m K) (with T in Kelvin)Surface temperatures: Th = 150 ?C Tc = 50 ?CASSUMPTIONSThe wall has reached steady stateConduction occurs in onedimension
